Particle hair growing in a weird direction
The hairs grow from the faces of the two rings in the direction that the normals are facing.  If you view normals in edit mode (by turning on the overlay


and setting the normal length) I suspect you will see something like this:

You want the normals from the top ring to face down.  To do that select all of the faces in the top ring and type SHIFT-N to recalculate normals.  If they're still facing up, open  the action box (in the lower left of the 3d view) and enable inside:


and you should see something like this:

Now your hair should grow down from both rings
